Abstract
1,245,163. Valve phase shift circuits. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 17 Jan., 1969 [18 Jan., 1968], No. 2897/69. Heading H3W. A circuit for producing a constant phase shift over a band of frequencies comprises a differential amplifier 10 with a signal source 3 connected, via an RC circuit R 2 C 2 to an input 11 and a feedback path connected from the output 13 to another input 12 via a network R 1 C 1 . The capacitor C 1 may be shunted by a further resistor, Fig. 3 (not shown). If C 1 R 1 =C 2 R 2 the phase shift is 90 degrees over the amplifier operating range.
